Specification of Letters Patent.

Patented Jan. 14:, 1908.

Application filed May 4. 1907. Serial No. 371.835.

To all whom it may concern:

Be it known that I, JOHN T. H. PAUL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Bottle-l/Vashels, of which the following is a specification.

The present invention relates, more particularly, to improvements in features of the bottlewashing machine shown and described in United States Letters Patent No. 827,388, granted to me on the 31st day of July, 1906.

The objects are to improve the step-by step drive of the rotatory rack to the end of rendering its motion smoother and avoiding the jar in starting and stopping the rack which attended its operation with the use of the former drive-means, and which tended to disorganize the mechanism of the machine, with the additional consequent advantage of enabling the rack to be driven at greater speed than formerly; to provide the upper socket-members for the bottles with internal rotatory brushes to operate against the bottoms of the inverted bottles for cleaning them and to provide a simple and novel vertical adjustment for these upper socketmembers, by which to readily adapt them to be raised and lowered and fastened in adjusted position, with relation to bottles of different lengths.

In the accompanying drawings, Figure 1 is a view of the improved bottle-washer in ver tical sectional elevation; Figs. 2 and 3 are sections taken, respectively, at the linesA and B on Fig. 1 and viewed as indicated by arrows; Fig. l is an enlarged broken view showing the bottlebottom brush-mechanism in vertical sectional elevation, the section being taken at the line C on Fig. 3, and

viewed in the direction of the arrow, in the position of contact of the pinion with its depressing cam; and Fig. 5, a view in elevation of the ring in which the bottom-brush member is supported and which contains opposite angular slots for permitting the adjustment of the lower ring of the upper bottlesocket relative to the bottom-brush.

While the aforesaid patent shows and describes means for automatically delivering the washed bottles in succession to a traveling conveyer, these features, namely the delivery mechanism and conveyer, may or may not be employed and are omitted in this case as having no bearing on the present improvements, which relate to the rack-drive and the bottom-brush, as hereinbefore mentioned. The other parts of the machine are or may be the same as shown and described in the patent, so that it is only necessary to refer to them in the present connection in a general way, sufficient to enable the present improvements to be identified with the former construction.

The base-frame 6 is surmounted by the pan 7 having a bracket 8 extending from one side and carrying on its upper end belted drive-pulleys 9 geared to the friction-drive 10 on the vertical shaft 11 of the rack 12, which shaft passes through the stationary sleeve 13 and carries on its lower end the gear 14 for rotating the shafts of the internal brushes. The vertical shaft 15, journaled in the pan and in a'horizontally extending frame-member 16, is geared by a crank-connection at 17 with the vertically rocking cradle-device 18, which raises and lowers the internal brush-stems 19 with the chambered cross-head 20, to which these stems are connected at their lower ends, this shaft carrying on its upper end the large 'gearwheel 21 meshing with a pinion 22 on the shaft 11 and also carrying, between its ends, a gear 23 for rotating the external bottle-brushes 24 and actuating the friction-device 25 for the upper rotary-socket members of the bottle-clamping devices. These socket-members constitute one of the features of improvement which will be more fully described hereinafter. The lower socket-members 26 for the bottle-necks are movable on guide-rods 27 extending between the upper and lower heads of the rack, and are suspended by springs 28 from an ad justable crown-like hanger 29 on the sleeve 13 to be depressed by a cam 30 on the lower end of the hanger. By moving into the lower part of a cam 31 on an extension of the frame-member 16, a stud 32 on a link 33 depending from the free end of the lever 34-, the friction-drive 10 rotates the shaft 11 to produce the several operations of the bottlewasher proper, including the opening and closing of a valve, at'35, by rocking the cradle-device 18, all as described in said patent.

To produce the requisite step-by-step rotation of the rack 12, with reference to which the rise and'descent of the head 20 and the opening and closing of the valve 35 are timed, the following described mechanism is provided:

On the upper end of the shaft 15, between the gear 21 and the frame-member 16, which in the present case is of the shape represented in Fig. 2, is secured to rotate with it a disk 36 having its periphery formed with a concave arc-shaped recess 37, and provided with a crank-finger 38 extending across the center of said recess. An antifriction roller 39 depends from the outer end of the crank-finger. disk 36 is centrally journaled .in the upper side of the horizontal framennember a starwheel 40 containing notches 41, shown as five in number, and equidistant apart, with concave arc-shaped recesses 42 in its periphery between notches conforming to the periphery of the disk 36. A gear-wheel 43 is provided below the star-wheel on its hub to mesh with an idler-pinion 44, which, in turn, meshes with a similar pinion 45 ona stub-shaft 46 journaled in the upper side of the framen1ember 16 and carrying to extend with its ends equidistant from the axis of the stub-shaft, a cross-head 47 having studs 48, 48, which are preferably anti-friction rollers, depending from its opposite ends. On the top 01 the upper rackhead 50 near its periphery are provided in circumferential series teeth 49, of which eight are shown in Fig. 3, equidistant apart. Each of these teeth is formed in the shape represented as a flange rising from the rack-head and is adapted to be straddled by the studs 48.

Rotation of the shaft 15 rotates the disk 36, in each rotation of which the finger 38, through the medium of the antifriction roller 39 upon it, engages a notch 41 in the star-wheel, to move it one stepon its axis and, through the idler 44, turn the pinion 45 and the cross-head 47 correspondingly. Thus turning the cross-head engages the stud on one of its ends with the side of the adjacent.

tooth 49, to rotate the rack on its axis, the stud guidingly following that side of the respective tooth until the opposite stud engages the opposite side of the next adjacent tooth, which then becomes embraced by the two studs. The proportions of the gears 44, 45, relative to the gear 43 is such that turningof the star-wheel the extent of one notch causes the cross-head 47 to make one-half of a revolution. In the position of the crosshead 47 shown in Fig. 3, its engagement with a tooth 49 looks the rack in its position of rest. In this manner the rack is rotated stepwise between reciprocations of the head 20, and its rotations are rendered smooth Without jar in starting or stopping, owing to the regular action of its immediate drivinggear. The similar arc-shaped recesses 42 shown to be provided in the periphery of the wheel 40 between the notches 41 by conforming to the arc of the periphery of the disk 36, tend to brake the wheel against undue turning under its inertia in rotating; and the Adjacent to the recess 37 provided in the disk enables it to clear the edges of the notches 41 in the wheel. This gear is an adaptation to the present purpose of the mechanical movement known as the "geneva.

WVhile the upper rotatory socket-member 51 of each bottle-clamp is the same in its general'function as in the aforesaid patent, it is now equipped with an internal rotary brush for scouring the bottom of a bottle held by it and is rendered vertically extensible and contractible to adapt it to be adjusted to bottles of different diameters.

On a horizontal circumferential flange 52 provided about the edge of the upper rackhead, is seated a ring 53 having external gear-teeth 54 and internal ear-teeth 55. An arcshaped flange 56 on tdie under side of the frame-member 1.6 extends over a considerable portion of the ring 53 to prevent it from rising from its seat. This ring is driven by the large gear 21 meshing with a small gear 57 on a shaft 58 ournaled in the framemember 16 and carrying a pinion 59 meshing with the outer gear 54. "At equal intervals about the upper rack-head are journaled in it, near its periphery, one being shown in each tooth 41, spindles 60. Each spindle extends through and beyond a bushing 61, rotatably suspended by 'a nut 62 surmounting the upper rackhead, and carries on its upper end a pinion 63, below which, and penetrated centrally by the spindle, is a cross-head 64 resting on said nut and having legs 65 depending from its end into sockets 66 formed on the rack-head and in which spiral springs 67 are confined about the legs, tending to raise to its highest position the pinion 63. Into the lower end of each spindle is screwed the stem 69 of a brush-device 63, containedwithin a bottle-clamp socket 51. Each socket 51 is formed of an outerring section 69, having a dished upper end 70 integral with the bushing 61 and containing openings 71, and about which is formed the circumferential flange 72 to engage frictionally with the gears 25, and an inner-ring section 73 provided with a downwardly flaring mouth 74 adapted to fit about the bottoms of bottles 75 of diflerent diameters.

at diflerent elevations; and the two rings are releasably clamped together by wingnuts 81 on the screw-stems.

Bottles 75 to be washed are confined in members 26 and 51 of the clamps; and in the V step-by-step rotation of the rack, the pinion .59 drives the gear-ring 53, which, by its engagement with the pinions 63 rotates them Screw-stems 76 project horizontally from to revolve the brushes 68 against the bottoms of the bottles. Water is supplied to the bottom-brushes through a pipe 82 on the framemember 16, having depending nozzles 83, 84, extending over the path described by the socket-members 51 in the rotation of the rack, to discharge into their dished upper ends and through the latter flow the water upon the bottom-brushes; the pipe 82 having a hose-connection S5 with any of the water-supplying pipes of the machine, as that containing the valve 35. An arc-shaped horizontal track 86, having a cam-end 87, is provided on the bottom of the frame-member 16 to extend in the path of the pinions 63 in the rotation of the rack, whereby when a pinion encounters the cam 87, it rides beneath the track 86 and is depressed with its spindle against the resistance of the spring 67 to bear the brush 68 against the respective bottle-bottom; and when the spindle clears the cam-track 86, the springs 67 raise the brush to its normal position. By loosening the wing-nuts 81 on the rings 69, the rings 73 are loosened and may be turned to turn the stems 76 on their seats in the slots 77, and raised and lowered and turned to bring the stems on different seats in said slots. Thus the lower sections 73 of the upper sockets 51 may be readily adjusted with reference to bottles of different diameters, varying within, say, about an inch.
